Myracing.com compiled data on Her Majesty's horses' wins and losses, and reported that she recorded 451 race wins with a win percentage of 15.9 per cent in that time period.

Last year alone, the Queen banked £557,650 (about $930,000) from her prized horses — the most earnings she's ever taken home in a year. So far she has earned £413,641 (about $690,000) this year, so there's still time to beat last year's record.

However, the Queen doesn't get to put all those earnings into the bank (sorry, royal offspring — no horse earnings for you!). According to Hello, the majority of the winnings go to the horses' trainers, which makes sense, as it's their hard work that turns those horses into champions.
